I have been silent recently partly because I have only just started to recover from being totally upstaged by my lovely granddaughter, Kiki. Seeing how her mother regularly sets her children little maths problems, I tried one on Kiki at breakfast one morning.
Grandpa: "Kiki, what's 11 times 12 times 13?"
[pause, followed by the triumphant stare - see pic]
Kiki: "Why do you want to know?"
Pass the Sanatogen....
